Application filed Novemberll, 1882. Renewed October 6, 1883. Again renewed June 18, 1884. Again renewed J' une 16, 1885.

.To all whom 15 may concern..-

Beit known that I, HERMON E. CUNNING- HAM, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in a Machine for Inserting and Olinching Staplesin Shoes, &c., which improvement is fully set forth in the following specification and accompanying drawings,

My invention relates to improvements in' machines for inserting clinching staples in shoes, dto.; and it consists of feeding, retaining, piercing, grasping, and driving devices, as will be hereinafter fully set forth.

It also consists of means for supplying staples of different lengths and thicknesses to the feed-chute, and operating the machine without changing the devices for lifting, piercing, clinching, 8vo.

Referring to the drawings, A represents the frame of the machine, and B represents the drivingshaft, which is suitably mounted on standards B of said frame.

C represents a spur-wheel, which is support-ed on one ofthe standards B and geared with apinion, a, Whig? is vkeyed (i ctherwisa` secured to the shaft p said Whee i C having, secured to or formed with it on one side a cam, C', which is adapted to bear against a sliding carriage, D, which is sustained on the frame A beneath the shaft B, the end of said carriage opposite to the icani C being formed into a head, within Whichl iis fitted a vertically-arranged staple-driver, E, and to the lower end1 of which is secured a pair of vertically-arranged ngers, F, between which the working end ofthe driver lE is located, said fingers being sufciently elastic to receive. and hold a staple inserted from below. ,I

G represents the feed-chute of the machine, the same being secured in position 1beneath the head ofthe slide or carrier D, and entend A, and guided in an opening in a supply box i or cup, J, which is supported on the frame below the carrier D, said bar being attached to a lever, K, which is pivoted to the frameA and connected with an arm, K', the upper end of which is fitted on an eccentric on the shaft B, whereby rising and falling motions are imiparted to the bar, it being noticed that the location of said bar is such that when it is raised to full extent its upper end is adjacent to the highest part of the feed-chute G. (See dotted linesFig. 2.)

Tothe frame below the carrier D is connected a horizontally-arranged slide, L, from which depends a stripper, M, of bifurcated shape, so located that when the bar H is at its highest point said stripper advances alongthe same and forces 'the staple which rests on the top thereof from its position and places it on the feed-chute G. Motion in one direction is imparted to the slide L by means of a pin or post, N, which passes vertically through a longitudinal slot, b, in the frame A, and a slot, b, in the carrier D, and is engaged by a lever or arm, P, which is pivoted to one of the standards B of the frame, saidarm being operated by a cam, Q, which is fixed to the driving-shaft B, whereby by the rotation of said shaft B the cam Q and arm P force back the slide L, and consequently the stripper M, ready for the advance motion of said stripper occasioned byaspring, B, which bears against the frame A and slide, or may be otherwise suitably applied. Y

S represents a staple-lifting bar whose upper end is bifurcated and so disposed as to -straddle the feed-chute at the lower end thereof, the same being mounted on the frame A and operated by levers S' S", through the medium of an eccentric on the driving-shaft.

To the box or cup J is pivoted a stapleholder, T, which extends parallel with the lifting-bar S at the side thereof, and has its 2 I l l upper end or nose turned inwardly toward the.

feed-chute G at or about the position occupied .by the second staple, so that at a proper time said nose presses said staple, thus holding the same and all other staples above it, the first or lowermost staple being left free to be re.

moved. The pressing motion of the stapleholder is occasioned by a swell or cam, U, formed on the side of the lifting-bar S, the lower end of the holder being adapted to come incontact with said swell or cam, the relieving or returning motion of the holder being occasioned by a spring, U', suitably applied.

To the end of the driving-shaft above the stapledriver E is secured a cam, V, and another cam, V', which are placed side by side, the cam V being fitted in a yoke, W,

' the head or holder of the awl, said catch serving to sustain the awl when elevated, when v the yoke W is .relieved of the cam V by the motion of the carrier I), as will be hereinafter set forth, said catch, however, being overcome when the awl is depressed.

Y represents a bed or anvil for holding the shoe or other article while the staples are being driven thereinto and clinched, the same being secured to the frame of the machine ory to the feed-chute, and in either case occupying a position adjacent to the lower end of the feed-chute. 1

The box or cup J has a depressed top,s`o as to direct the staples to the center over the feed-bar H. In order to provide means for feeding staples of different sizes, I employ an additional box or boxes and connect them by a coupling, Z, and fit the boxes to the frame or bed so as to slide in the transverse direc-v tion of the machine.

Each box or cup has connected to it, as at Z', a feed-chute, G, and a holder, T, the lifting-bar S having a swell or cam, U, on each sid 1; so as to be engaged by either holder. Furthermore, each box or cup has a connected feed-bar, H, and the end of the lever K under the box or cup has pivoted to it a saddle, H',-

which is adapted to have the lower end of either feed-bar placed upon it, whereby when the leverK is raised the relative feed-bar will also be raised, it being noticed that the feedbar is not fixed to the saddle.

Z represents a lever, which is pivoted to the frame or bed of the machine and connected with one of the boxes or cups, whe eby t le coupled boxes or cups may be conv nien l`y moved as one and shifted in proper position over the lever K, whereby the feed-bar may `be operated andthe desired size of staples raised and presented for the action of the stripper.

The box or cup is supplied with staples, power applied to the drivingshaft, and the shoe or other article to be stapled'placed on the bed or anvil Y. The bar H rises and works its way through' the staples, taking such by the head or crown as is in its path and raising 1t or them to the top of the box or cup. The stripper advances and clears thebar of the staples and moves them toward and on the feed-chute, down which they ride to full extent. The awl descends and pierces the shoe, and then rises to its normal position, the catch d then engaging with the awl head or holder. The li tiEgbarS now rises and forces-the first staple to the` ingcis F, which grasp the same, tli'e second and remaining staples being stationary, controlled by the holder, as has been stated. The earrler D then advances and forces ahead of it the awl with its connected yoke, the latter leaving its cam and vremaining suspended by the spring-catch d, and the staple-driver and iingers being placed above the bed or anvil Y, with the legs of the staple in position to enter the perforations made by the awl.

It wi-ll'now be seen that the cam V is direetly above the head of the staple-driver, and it is elvideut that the rotation ot said cam depresses the stapledriver, thus forcing the staple into .the shoe or other article, .the legs beingclinched thereon-by the action of the bed or anvil. The stripper returns to its normal position, the staple-driver rises, and the head W is carried 4back,.thus restoringthe awl, staple-driver, and fingers to their normal position, the yoke Wagain encircling the cam Vthi eturn motion of thehead being achpaated by the :ation of@ spring, wc, su' abi# lapplied, or by the cam C, which may be constructed to accomplish the same. `The feed-liar rises and the stripper advances, so that the feed-chute is further supplied with staples, the lifting-bar is elevated, the` awl pierces the article, and the subsequent operations, similar to those stated, are repeated.

Having thus described myinvention, what I claim as new, and desire to secure by ILetters Patent, is g 1. In a staple-driving machine, a box or cup for staples and a single staple-feeding bar Working up through the same, in combination with the slide L, moving longitudinally across the top of said cup, a stripper, M, carried by said slide, and a chute to which said stripper delivers the staples after removing them from said staple-feeding bar, substantially as .and for the purpose set forth.
